Hold-down timers are used in dynamic routing protocols to prevent the formation of routing loops. When a route is reported as unreachable, the hold-down timer starts, and during this time, further updates trying to reinstate the route are ignored. This prevents the possibility of routing updates that could cause a loop from being accepted immediately, providing a window for the network to converge on a new topology. This statement is accurate as the intent of hold-down timers is indeed to stabilize the routing table, thus making the true statement correct. However, while hold-down timers can help prevent routing loops, they are not the only mechanism in place to do so, and their implementation must be done carefully to avoid unnecessarily increasing convergence time.
